Speed up debug stub test by using TCP_NODELAY socket option.
Speed up debug stub test by using TCP_NODELAY socket option.

We currently set TCP_NODELAY for the debug stub socket but not for the test
socket. Setting this option for both sockets speeds up the test 4 times.

BUG= none
TEST= run_debug_stub_test
